Hey @yoni A,

Any chance you could send your model or a sample model showing the problem?

Thanks.

Hi @yoni A,

I was unable to open your model, but I can provide a sample model if you could explain two constraints:

1) How often does the processor pull the items? (ex. once a day, once per cycle, etc.)

2) How many item types do you plan on having?

pull-schedule.fsm

take a look at this one @Tanner Poulton, items must be pulled from queues based on the schedule (see global table 150 line, 1st line) and (global table QW 2do line)

@yoni A,

My best initial suggestion is to try using a Date/Time Source in Process Flow to create your "orders". Attached is part of your "QW Line Requested Qty" table inserted into the Source Arrivals.

Because these tokens will be the proper quantity and respective type, you can use them to pull items from a list and move them to the central processor.

I would recommend sending all of the items from each queue into a list that is partitioned by Type.

If you'd like an example or clarification for any of this, let us know. Hopefully it at least points you in the right direction.

@yoni A There is a black processor and 3 yellow ones, which one would you like to control with a schedule?

Here's a model that should do what you're looking for:

yoni-help-pull-quantity.fsm

Essentially, the quantity and delay times are referencing the table so that they pull at the appropriate times.
